Steven Rostedt (Google) 575b76cb88 tracing/probes: Handle system names with hyphens ... When creating probe names, a check is done to make sure it matches basic C standard variable naming standards. Basically, starts with alphabetic or underline, and then the rest of the characters have alpha-numeric or underline in them. But system names do not have any true naming conventions, as they are created by the TRACE_SYSTEM macro and nothing tests to see what they are. The "xhci-hcd" trace events has a '-' in the system name. When trying to attach a eprobe to one of these trace points, it fails because the system name does not follow the variable naming convention because of the hyphen, and the eprobe checks fail on this. Allow hyphens in the system name so that eprobes can attach to the "xhci-hcd" trace events.
